I hope you realized that the Handbrake presets might not be compatible between platforms. You're going to need some magic numbers to create a file of the best quality while maintaining compatibility between the two devices.

So you're going to be using Handbrake, again.

I hope you're not looking for iPod/Phone compatibility in addition. In my opinion you should just encode the DVD video for each device.

I've got a ps3 and I find it so temperamental with playing mp4s. I've been converting a load of files and dvds to mp4 to stream to my ps3 and it's so unreliable - some files it plays fine, but others struggle. I'm going to get a atv to stream to as it will be so much easier - and a lot better UI!

I've also found that a load of mp4's that used to play on the ps3, now don't since tagging them with metax - don't know if this is just a coincidence that they stopped working after tagging or if the ps3 just can't handle the files.

I forgot this was Sony I was dealing with. Sony always wants their own formats (remember that stupid Atrac music file they were pushing). I guess Apple won that battle with their AAC/mp3 compatability.

I'll just stick with the Apple Handbrake video m4v format. I know it always works on both my PC/MAC and Apple TV.
